Function lbv 

Source 
pub fn lbv(
    field: &[f64],
    mask: &[u8],

    params: &LbvParams,
    progress: impl FnMut(usize, usize),
) -> Result<(Vec<f64>, Vec<u8>), InputError>
Expand description

LBV background field removal (LBV.m)

§Arguments

  • field - Total field in ppm (nx * ny * nz)
  • mask - Binary mask (nx * ny * nz), non-zero = brain
  • grid - Volume dimensions and voxel sizes
  • params - LBV parameters, with the scan’s field strength and echo times
  • progress - Progress callback (step, steps): one step per multigrid level, and the finish

§Returns

(local_field, interior): the local field in ppm as LBV.m returns it (defined on the interior; see the module docs for the voxels around it), and LBV.m’s interior (the mask minus peel + 1 layers).
